Particles and dynamics

* Somehow I got this Java script to work. As mentioned in the posting #13, it is used to distort a C3D mesh along the curvature of a spline. This is then used as a base for a particle mesh.
* As a result you get a square set of items which are following a sinoidal curve.
* No idea, if this can be used in your project.

You guys are very impressive.

Hi Helmut

May I have the .JAS file you'd built so that I can poke around it. I've tried for a few hours to duplicate the setup, above. I'me not getting even close to the results shown in that. I think, I'm using that script you'd mentioned but it's very unclear how to apply it (correctly). I generally like to figure things out myself but I'm just stumped.

Cheers
 
Hi Jesse

Maybe this will help, I used the Wavy 3D Plane script and a Particle Mesh.
The parameters that I animated are the Wave h Start and Wave w Start fields.

Hi Jesse,

1 In the scripting section of this website you can locate and download any required Java scripts. Simply move the script(s) into the correct folder (in this case Polygonobj) under Application Support / Cheetah in the Library.
2 As Frank has pointed out, this seems to be a script coded by Master Hiroto. There is a link to Hiroto Tsubaki´s website given in the scripting section.
3 You need to restart the C3D application for the script to be selectable in the menue.
4 Then experiment and tweak the parameters available to generate the specific sine distortion you need for your project. The primary parameters to be animated are wave w & wave h start, possibly from 0 to 1. No idea if you need to fiddle with wavelength λ and amplitude A.

* You should get something which looks like a sting ray flapping through its maritime habitat. ZooHead´s example contains all you need for constructive experimentation.

Hi ZooHead!

Yes! Extremely helpful. Essentially, I was using the wrong script! I've learned quite a lot from this file. Cheers!

Hi Helmut

Both, ZooHead and your help, got me over the crux. TY and cheers
